The Backcountry Access Tracker4 Avalanche Beacon has a lot to live up to. It comes, after all, from a long line of beacons that are known for their ease-of-use and simple, no-nonsense design. This iteration upholds those standards, with all the same functions and features as the Tracker3, only now in a beefier, bombproof design. The Tracker4 is built with a rubberized over-molded case that's perfect for us 100-day skiers that are tough on our gear, and it boasts a larger LED display for even easier handling in an emergency.
